Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety while working on the electrical system.
Allow the vehicle to cool down before proceeding.

2. Inspect Fuel Level Sensor

Tools Required: Multimeter, socket set, screwdriver
Remove the rear seat or access panel to reach the fuel tank access.
Disconnect the fuel level sensor connector.
Measure the resistance across the sensor terminals using a multimeter.
- If the resistance is outside the manufacturer's specifications, proceed to replace the sensor.

3. Replace Fuel Level Sensor (if necessary)

Tools Required: Socket set, torque wrench, new fuel level sensor
Disconnect the fuel lines from the fuel pump assembly if applicable.
Unbolt the fuel pump/sensor assembly from the fuel tank.
Remove the old fuel level sensor from the assembly.
Install the new fuel level sensor in the assembly.
Reassemble the fuel pump/sensor assembly back into the tank and secure it with bolts.

4. Reconnect Components

Reconnect the fuel lines and the electrical connector to the fuel level sensor.
Reinstall the rear seat or access panel.
Reconnect the battery.

5. Test

Start the vehicle and observe the fuel gauge for proper operation.
Perform a gauge sweep test to ensure full functionality.
